Description
Zuteil- bzw. Eintragevorrichtung für Behälter mit innerem Überdruck In der Technik wird oft 'die Aufgabe gestellt, körniges Schüttgut in .einen Raum einzuschleusen, der gegenüber der Atmosphäre einen Überdruck besitzt. Es ist bekannt, hierzu Förderschnecken zu verwenden, die das aufzugebende Gut verdichten und den erzeugten Gutpfropfen in den Raum höheren Druckes hineindrücken. Auch ist es bekannt, außerdem am Ende der Schnecke nach Art von Rückschlagventilen Klappen anzuordnen, die beim Ausbleiben des Fördergutes den Überdruckraum selbsttätig von der Atmosphäre abschließen. Die vorliegende Erfindung will nun eine Verbesserung der bisher bekannten Zuteil- bzw. Eintragevorrichtung der geschilderten. Art vorschlagen.Allocation or entry device for containers with internal overpressure In technology, the task is often set to move granular bulk material into a room to smuggle in, which has an overpressure compared to the atmosphere. It is known, to use screw conveyors for this purpose, which compress the material to be fed and the Press the generated plugs into the space of higher pressure. It is also known also to arrange flaps at the end of the screw like check valves, which automatically removes the overpressure space from the atmosphere if the conveyed material is missing to lock. The present invention seeks to improve on the previously known Allocation or entry device of the described. Kind of suggest.
Bei der Einrichtung gemäß vorliegender Erfindung wird das an sich bekannte Rückschlagventil gleichzeitig als sicher wirkendes Absperrventil ausgebildet. Kennzeichnung seiner Bauweise ist die zentrale Führung des Ventilkörpers. Der Austritt des Fördergutes aus dem Schneckenraum geschieht gleichmäßig längs des Dichtungsumfanges des Ventilsitzes. Eine elastische Ringscheibe wird durch den Kohlenstrom von ihrem Sitz nur jeweils an dem Teil des Umfanges abgehoben, an dem der Kohlenstrom aus der Förderschnecke austritt. Für die. Abdich-Jungsringe ist als Baustoff Gummi besonders geeignet, doch können auch dünne Stahllamellen entsprechende Anwendung' finden. Die Bauweise ergibt einen sicheren Abschluß gegen einen Gasaustritt durch die Eintraggvorrichtung.In the device according to the present invention, this becomes in itself known check valve designed at the same time as a reliable shut-off valve. Its design is characterized by the central guidance of the valve body. The exit of the conveyed material from the screw chamber happens evenly along the circumference of the seal of the valve seat. An elastic washer is created by the stream of coal from her Seat lifted only on the part of the circumference where the coal flow comes from the screw conveyor emerges. For the. Abdich-Jungsringe is a special building material rubber suitable, but thin steel lamellas can also be used accordingly. The design results in a secure seal against gas leakage through the entry device.
Die Abbildung zeigt ein Beispiel des Er findungsgedankens. An der Stelle A wird der Zuteilvorrichtung das in den Raum B, in dem ein Überdruck herrscht, zu schleusende Gut aufgegeben. Die Schnecke S bringt das Gut gegen ein Rückschlagventil R, das unter dem Materialdruck öffnet. An denn öffnungsquerschnitt ist das Material so stark zusammengedrückt, daß eine Gasströmung vom Innern des Überdruckraumes nach außen durch das Material nicht eintreten kann. Der überdruck im Raum B bleibt somit während des Einschleusens erhalten. Die Aufgabeschnecke S ist zweckmäßig zweigängig ausgeführt. Sie läuft in einem Gehäuse G, das eine Stahlbüchse C zur Verhütung von Verschleiß besitzt. Das Rückschlagventil R ist erfindungsgemäß gleichzeitig Absperrventil. Durch die Spindel P kann der Kegel des Rückschlagventils R fest auf den Sitz gepreßt werden. Die Flügelmutter M dient zur Verstellung der Federspannung des Rückschlagventils R. Im besonderen besitzt das Rixekschlagventil R einen federnden ringförmigen Teller, der zugleich in sich elastisch ist. Dieser Teller wird an der Austrittsstelle des -Materialstromes von seinem Sitz abgehoben. Dabei öffnet nur der Teil des Ventilquerschnitts, der den Materialquerschnitt umschließt.The figure shows an example of the inventive concept. At the Point A is the allocation device in the room B, in which there is overpressure, abandoned goods to be smuggled. The screw S brings the material against a check valve R, which opens under the material pressure. Because the opening cross-section is the material so strongly compressed that a gas flow from the inside of the overpressure chamber to cannot enter outside through the material. The overpressure in room B thus remains received during the smuggling. The feed screw S is expediently two-flighted executed. It runs in a housing G, which is a steel sleeve C to prevent Owns wear and tear. According to the invention, the check valve R is at the same time a shut-off valve. The cone of the check valve R can be pressed firmly onto the seat by means of the spindle P will. The wing nut M is used to adjust the spring tension of the check valve R. In particular, the Rixekschlagventil R has a resilient ring-shaped plate, which is elastic in itself at the same time. This plate is at the exit point of the -Material flow lifted from its seat. Only the part of the valve cross-section opens which encloses the material cross-section.
